Your post was in the Bible Discussion thread, so making your way back there and then scrolling down til you find it is one method.
Also you can go to your profile (click 'pavalam' on on the top of the page near the right) and it will show you your most recent posts. If you have friends it will also show their most recent activity. If you only want to see your posts, and not your friends, you can click pavalam under 'My Activity'.
As a side note, to make sure you don't confuse yourself, or others, in the future, the section of the site you're in now is the Forums. The Chat Rooms are a separate section that you have to take an extra step to enter. Chat Rooms are real time, whereas forums, as you see, are not real time.
